DETAILED DESCRIPTION

[0024] In order to enable the above-mentioned purpose, features and advantages of the utility model to be more clearly understood, the utility model will be further described in detail below in conjunction with the drawings and specific embodiments, and the embodiments of the application and the features in the embodiments can be combined with each other without conflict. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] The utility model provides a spherical microreactor in one aspect of embodiment, aims at solving the problem of the existing microreactor volume is too large, internal space resource is not fully utilized, reaction efficiency is low and the like.

[0026] Embodiment 1:

[0027] As Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown in the figure, in order to solve the above problems, the spherical micro-reactor provided by the embodiment comprises a feed inlet 1, a reaction path and a discharge outlet 2 connected in sequence, and further comprises a plurality of spherical shells 3, a channel type reaction path 31 and a connecting path 32; two adjacent spherical shells 3 are nested and abutted; the outer surface of the inner spherical shell 3 and / or the inner surface of the outer spherical shell 3 at the abutted portion of the adjacent spherical shells 3 is provided with the channel type reaction path 31, the channel type reaction path 31 is arranged in a bent manner from top to bottom along the abutted portion, the starting end is located at the top of the spherical shell 3, and the terminal end is located at the bottom of the spherical shell 3; the channel type reaction paths 31 are connected in sequence through the connecting path 32 to form the reaction path; the channel type reaction path 31 arranged at the abutted portion of the plurality of spherical shells 3 can fully utilize the internal space of the micro-reactor, and the reaction liquid can increase the collision times and mixing degree of the reaction liquid by passing through the reaction path arranged in a plurality of bending manners; in the micro-reactor, the reaction liquid enters the micro-reactor from the feed inlet 1, sequentially flows through a plurality of bending paths along the channel type reaction path 31, and forms a reaction path with a plurality of channel type reaction paths 31. The channel type reaction path 31 bends and extends downward along the inner surface and / or the outer surface of the spherical shell 3 until the final discharge outlet 2. Each channel type reaction path 31 is connected to each other and forms a complete reaction path.

[0028] Since the channel type reaction path 31 has a plurality of bending paths, the reaction liquid will collide multiple times when passing through the path, thereby increasing the mixing degree of the reaction liquid. In addition, since the plurality of channel type reaction paths 31 are arranged inside the spherical shell 3, the internal space of the micro-reactor is fully utilized, thereby increasing the reaction time and reaction efficiency of the reaction liquid.

[0029] As shown in the figure, Figure 2 and Figure 3 As shown in the figure, the channel type reaction path 31 further comprises a spiral channel 311, the spiral channel 311 is arranged in a spiral manner from top to bottom on the outer surface of the inner spherical shell 3, the spiral manner of the spiral channel 311 can be counterclockwise or clockwise from top to bottom, or the reaction efficiency can be improved by alternatively arranging spiral channels 311 in different directions. And the inner surface of the outer spherical shell 3 together constitute the channel type reaction path 31. In addition, a certain number of holes can be dug on the surface of the spherical shell 3 in order to more flexibly carry out the entry and exit of the reaction liquid. The holes can be designed according to actual needs, for example, a plurality of holes can be arranged at the top and the bottom in order to better carry out the feeding and discharging operations. The spiral arrangement of the channel type reaction path 31 can more fully utilize the surface area of the spherical shell 3, increase the length of the channel type reaction path 31 between the adjacent spherical shells 3, thereby increasing the collision times and mixing degree of the reaction liquid and enhancing the reaction efficiency.

[0030] Further, a vertical through hole 4 is arranged at the center of the spherical shell, and the connecting path 32 and the vertical channel 313 are arranged in the vertical through hole 4, so as to provide space for the connecting path 32 and the vertical channel 313 to be connected to the channel reaction path 31 more closely. Through the vertical through hole 4, the worker can also check whether the connection between the connecting path 32, the vertical channel 313 and the channel reaction path 31 is close, so as to ensure the reliability and stability of the reaction path.

[0031] Further, the number of layers of the multi-layer spherical shell 3 is not less than 4 and is a double number, and the adjacent channel reaction paths 31 are connected end to end through the connecting path 32 and the vertical channel 313. Since the number of layers of the multi-layer spherical shell 3 is a double number, the number of segments of the channel reaction path 31 is a single number. Through the end-to-end connection of the multi-segment channel reaction path, when the starting end of the first segment of the channel reaction path is located on one side of the feed port 1, the end of the last segment of the channel reaction path is located on one side of the discharge port 2. This arrangement makes the last segment of the channel reaction path not need to pass through the entire vertical through hole 4, which can reduce the length of the connecting path 32 and the vertical channel 313, save the internal space of the vertical through hole 4 and the internal space of the spherical shell 3, and make the reactor more compact and efficient.

[0032] Further, the polygonal cross-sectional shape can be a square, a regular hexagon or other polygonal shape, and the specific shape can be selected according to actual needs. The edges of the cross section can be arranged in a circular arc shape, which can reduce the flow speed of the reaction liquid at the edge corners, reduce the loss of the reaction liquid at the edges, and improve the reaction efficiency. At the same time, the cross-sectional area of the channel reaction path can gradually decrease along the flow direction, which can gradually increase the flow speed of the reaction liquid, increase the residence time of the reaction liquid in the channel reaction path, and improve the reaction efficiency.

[0033] In addition, the cross-sectional area of the channel reaction path can be provided with holes of different sizes at different positions, which can control the flow speed of the reaction liquid at different positions and realize reaction control under different reaction conditions.

[0034] Further, in order to facilitate cleaning and maintenance, the outermost shell of the multi-layer spherical shell 3 adopts a detachable hemispherical structure, which is convenient for maintenance and replacement of the interior. Two hemispherical shells 3 are connected and tightly butt-jointed through fastening devices 5 (such as threads, snap rings, etc.), so that the integrity of the multi-layer spherical shell 3 is more stable and reliable, and the internal multi-layer shell can also adopt a hemispherical structure, two symmetric hemispherical shells are bonded to form a spherical shell, and the assembly is completed from the inside to the outside in sequence during assembly. The 3D printing technology can be used to directly print the entire multi-layer spherical micro-reactor, including the multi-layer spherical shell, the channel reaction path and the connecting path. This method avoids the connection and sealing problems in the traditional assembly process, and can accurately control the internal structure of the micro-reactor.

[0035] Meanwhile, to prevent external environmental interference with the interior of the multi-layered spherical shell 3, a sealing plate is provided at each vertical through hole 4 of the hemispherical shell 3. The sealing plate is also provided with a sealing plate opening for connecting to the inlet 1 and the outlet 2 to facilitate the entry and exit of fluid.

[0036] In addition, this structure can be reinforced and sealed as needed to ensure the safety and stability of the system. During use, the hemispherical housing 3 can be easily disassembled for internal cleaning and maintenance, thereby improving the equipment's lifespan and efficiency.

[0037] like Figure 5 and Figure 6 As shown, the spherical microreactor further includes a circulation path 6, with both ends of the circulation path 6 connected to the two ends of the reaction passage. The end of the reaction passage is provided with a control valve 61 to control the flow of the reaction liquid in the reaction passage to the circulation path 6 or to the discharge port 2. By setting the circulation path 6 and the control valve 61, the reaction liquid in the spherical microreactor can achieve closed-loop circulation, thoroughly realizing the complete fusion between raw materials, making the reaction more thorough and better meeting the requirements.

[0038] Furthermore, the control valve 61 includes a gate body 611, an actuator 612, and a control system. The gate body 611 is located at the intersection of the reaction passage, the circulation path 6, and the outlet 2. It prevents the reaction liquid from flowing out of the outlet 2 and allows the reaction liquid to enter the circulation path 6 for recirculation. The drive end of the actuator 612 is connected to the gate body 611 and drives the gate body 611 to move, thereby blocking the outlet 2 or the circulation path 6. The control system, through a remote connection, can control the actuator 612, thereby controlling the opening and closing of the circulation path 6, allowing the reaction liquid to circulate between the reaction passage and the circulation path 6, achieving complete fusion of the raw materials. This design allows for a more thorough reaction in the spherical microreactor, better meeting the required conditions.

[0039] Furthermore, the valve body 611 of the control valve 61 is made of a corrosion-resistant material, possessing excellent corrosion resistance and adaptable to various reaction liquid environments. The actuator 612 can be electric or pneumatic; a suitable actuator 612 is selected based on specific application requirements, thereby ensuring the stability and reliability of the control valve 61. Simultaneously, the control system can monitor parameters such as the flow rate and pressure of the reaction liquid via sensors or other control devices, automatically controlling the flow direction of the reaction liquid as needed to achieve optimized control of reaction conditions, thereby improving reaction efficiency and yield.

[0040] Further, the spherical micro-reactor further comprises a fluid pressurizing device 7 arranged in the central cavity of the spherical micro-reactor and acting on the connecting path 32 and the vertical groove 313, which ensures the pressure stability of the reaction liquid through the fluid pressurizing device 7, wherein the fluid pressurizing device 7 comprises a pressurizing pump, a pressurizing membrane and a control system, the pressurizing pump is connected with the pressurizing membrane, the pressurizing membrane is wrapped outside the connecting path 32 and the vertical groove 313, and the control system controls the start-stop of the pressurizing pump and the folding and unfolding of the pressurizing membrane, so as to realize the pressurization of the reaction liquid. By arranging the fluid pressurizing device 7, not only the pressure stability of the reaction liquid can be ensured, but also the reaction liquid can be more uniformly distributed in the spherical micro-reactor, and the reaction efficiency is further improved.

[0041] In use, first, the reaction raw materials are input into the reaction channel through the feed port 1, then the flow direction of the reaction liquid is controlled by the control valve 61, the circulating flow path 6 is started, the complete fusion between the raw materials is realized, and the pressure stability of the reaction liquid is ensured by using the fluid pressurizing device 7. After the reaction is completed, the flow direction of the reaction liquid is controlled by the control valve 61, and the reaction product is discharged through the discharge port 2. If it is necessary to overhaul or maintain the inside of the reactor, the hemispherical shell 3 can be disassembled for operation.

[0042] Example 2

[0043] The spherical micro-reactor in the embodiment is basically the same as that in example 1, and the difference lies in the arrangement of the groove type reaction path 31.

[0044] As shown in Figure 4 The groove type reaction path 31 is composed of a plurality of annular grooves 312 and vertical grooves, the annular grooves 312 are horizontally arranged on the outer surface of the inner spherical shell 3, and adjacent two annular grooves 312 are connected through the vertical grooves. The top and bottom of the groove type reaction path 31 are respectively connected to the connecting path 32 and the vertical groove 313. Compared with example 1, the groove type reaction path 31 in the embodiment can simplify the processing difficulty in the micro-processing process, while ensuring the length of the reaction channel. The working principle and the use method are similar to those of example 1, and the high-efficiency and stable reaction process can be realized.

[0045] In the description of the utility model, it needs to explain, the orientation or position relation that the term "upper", "lower" and the like indicates is based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and it is not indicated or implied that the device or element indicated must have a particular orientation, a particular orientation structure and operation, therefore it cannot be understood as the limitation to the utility model.

[0046] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, term "assemble", "communication", "connection" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be direct communication, also can pass through intermediate medium indirectly communicates, can be two elements inside communication.For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.In addition, in the description of the utility model, unless otherwise stated, the meaning of "a plurality of" is two or more than two.
